Stockton University has one of the largest closed loop geothermal system in North America. It provides heating and cooling for the university academic facilities. The well field comprises of a grid of four hundred wells bored to a depth of 130m. The ground is composed of three aquifers of saturated sand sandwiched between confining beds and transition layers of sand and clay. The purpose of this ...

O objetivo deste trabalho foi modelar a perda de umidade de bananas Caturra com os modelos empíricos e com o software COMSOL Multiphysics, definindo os coeficientes convectivo de transferência de massa e difusivo. O valor obtido para coeficiente de difusão, com base no ajuste matemático da 2ª Lei de Fick para cilindros foi de 1,89.10-9 m²/s. O valor do coeficiente convectivo de transferência de ...

A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is a universal gate; any logic operation can be performed with various combinations of NAND logics. Many ...

1. Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale range since accurate high spatial resolution measurements of electrical properties are of great interest ...

In the medium term, gas hydrate reservoirs in the subsea sediment are intended as deposits for carbon dioxide (CO2) from fossil fuel consumption. This idea is supported by the fact, that CO2 hydrates are more stable than methane hydrates at certain conditions. The potential of producing methane by depressurization and/or by injecting CO2 is studied in the frame of the research project SUGAR. ...

Hot Isostatic Pressing (HIP) has been selected as a means of treating calcined high level waste (HLW). The process combines high temperature and pressure to densify the HLW in to a mineral similar to the geologic formulation of granite. This study uses COMSOL to predict densification and shape deformation of a stainless steel can filled with HLW. Two approaches were used to model ...

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The Electromagnetic Waves (emw) interface of COMSOL Multiphysics® was extensively used during the analysis of all our ...

A ball is in contact with a plane, and a lubricant separates the two surfaces to decrease friction during their relative motion. To avoid wear, the lubricant film thickness should be higher than the surface roughness. The goal of this paper is to show how it is possible to solve efficiently the problem of elastohydrodynamics lubrication with COMSOL Multiphysics®, using a PDE (Partial ...
Modeling of Wettability Alteration during Spontaneous Imbibition of Mutually Soluble Solvents in Mixed Wet Fractured Reservoirs - new

Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production mechanism. Initially, the solvent moves with the imbibing brine into the core. However, upon contact with oil, as the ...

Hydrophobic meshes are a new, promising technique for the recovery of spilled oil in the ocean. They allow to recover and store oil, while filtering it from the surrounding water. They are clean, efficient and can be used in continuously. These meshes have one drawback, however: if they are submerged too deep under the water level, the high pressure will cause presence of water in the recovered ...
